Fixed old-style function definitions, dropped unused variables, renamed
signal to xtm_signal (it shadowed a previous global declaration from
signal.h,) dropped the G_UN/LIKELY calls, missing includes and casted
here and there.
The task-manager-*.c files /would/ have to be individually fixed.
<sigh>
I started to rename "Show sytem processes" to "Show all processes"
and included a GtkTreeModelFilter in between the GtkListStore and
GtkTreeView but nooooo... I had to write private code to sort the
columns. In fact the GtkTreeViewColumn class assumes the model to
be sortable but GtkTreeModelFilter is not, although it provides an
accessor function to the underlying model which is.
And not to mention that understanding GtkTreeViewColumn is a task
on its own! Having the code under the hand is the only exit.
</sigh>
This commit is the second of an incremental serie. There will be other
commits with the information about tasks and the support for BSD and
Solaris once things are settled.
The TaskManager class is build with a new source task-manager-linux.c
that provides functions specific to the Linux implementation. It has
functions to read the usage of the memory/swap and the CPU.
Added the TaskManager class to hold system information and tasks.
Currently it provides username and hostname based on POSIX functions.
The Swap is now part of the system information and is being displayed in
the statusbar.
The statusbar is created since a separate widget class and has three
different labels (settable through properties) for CPU, memory and
number of processes. This makes it more convenient to change one or
another value and it gives a nicer look.
Changes touching the build:
- Bumped version to 0.5.0.
- Removed dependency on Xfce libs (it only depends on GTK+-2.0.)
- Updated Makefile with new source files.
- Build ChangeLog through a script (remove it from source tree.)
More generally speaking, the interface is build on top of a GtkBuilder
UI definition, with a personal GtkTreeView and a Settings GObject to
update the information shown on the interface on changes. All the code
is being written with GObjects which will make it a lot easier to
separate GUI code and system code.
